Company email (June 2013):
"Our stout, listed as "Colony Oatmeal Stout" on your website is now branded as "Back Road Stout." More importantly, the Iowa Pale Ale is now vegan friendly. Isinglass finings may have been used in the past, but they have not been used in the past 2 years that I have been brewing for the company. There is no plan, nor is there a need, to return to fining the IPA."

UPDATE:
From Brian:
"My contact with them has now stated that their current batch of the Iowa Pale Ale is vegan friendly, but once summer gets here and the demand goes up they are more likely to begin using the product once more."

Company email:
All of our beers except for the Iowa Pale Ale are vegan friendly.
